To all 107mm t may con/:ern:

Be it known that I, Gns'rar A. CAnLsoN, a citizen of Sweden, who have taken out first papers for citizenship in the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Curtain-Rods, of which the following is a specification.

This invention relates particularly to flexible curtain-rods, such as are commonly employed for Sash-curtains, and more especially to-curtain-rods which comprise a close- Wound spring Wire coil, or coils. The primary object is to provide a simple and effective connection between the coil or coils comprising the curtain-rod and the brackets which are adapted for connection with a window-frame, or sash.

The invention is illustrated in the accompanying drawing, in Which Figure 1 represents a broken plan view, showing the curtain-rod applied to a sash or Window-frame 'by means of the improved bracket connections; Fig. 2, a broken elevational view of the same; Fig. 3, a broken elevational view showi the device in somewhat modiedform; lig. '4, a broken sectional View taken -as indicated at line 4 of Fig. 2; Fig. 5, a broken sectional view showing the form of connection used in Fic. 3; and Fig. 6, a broken sectional vview illustrating a further modification of the de vice.

Referring to Figs. l, 2 and 4, A represents a Window-trame, or sash; B, a flexible curtain-rod comprising a close-Wound, resilient coiled Wire section or sections; and C, the improved bracket connection between the iexible curtain-rod and the sash or frame. The rod B may comprise a length of close Wound piano steel Wire, as indicated in the drawing; or it may comprise a pair of scctions of coiled Wire and an intermediate rod-section connected with the coiled Wire sections, as illustrated, for instance, in my co-pendino application No. 259,965, filed of even datetherewith.

Each of the brackets C comprises a baseportion 1 adapted' to be connected with the sash by means of screws, and an arm l equipped with a p longitudinally curved sleeve, or channel, l". The end-portion of the coiled Wire member B extends freely, but snugly, through the curved sleeve 1l and is secured therein by means of a pm, or short rod, 2, which equipped with a knob, or handle, 2*. The member 2 Vis a straight member. In makin the connection, the end-portion of the coiled Wire member B is slipped through the curved sleeve lb until the end projects somewhat, the pin 2 is then inserted, and the member B is then allowed to contract until the end-portion is drawn into the sleeve, as appears from Fig. 4. The introduction of the member 2 creates a binding action, inasmuch as the coiled Wire member cannotV freely follow the curve of the sleeve '1". In forming the connection, the member B is stretched suiliciently to give it the desired tension and the connection is formed in the manner shown in Fig. 4. When it is desired to disconnect the member B from the bracket C, this may be accomplished by stretching the member B and forcing the end-portion through the sleeve, and then withdrawingthe pin or plug, after which the end-portion of the coil will slip freely through the curved sleeve.

In the construction shown-in Figs. 3 and 5, C1 represents the bracket. In this case, the curvatureof the sleeve 1 is in a plane parallel with the sash, or frame, A. The pin or plug is designated 2b. Its action is the same as in the inst-described construction.

In the modificationshovvn in Fig. 6, C2 represents the bracket, which in this case is equipped with a straight sleevellb. The coil B is inserted through the sleeve, and a pin, or plug, 2 is inserted into the end of the coil, the pin being provided with an oil-set or deformation 3. When the end-portion ot' the coil is withdrawn into the sleeve, a binding action results by reason of the off-set 3, so that the wire coil will be securely held in the tube.

In each of the illustrations given, the pin orplug employed is adapted to produce a deformation of the wire coil with relation to the channel or' the bracket. so that a binding action is attained which effects a secure connection between the flexible curtain-rod and the bracket.

The improved device is inexpensive, neat' in appearance, thoroughly adapted to its purpose, and capable of being manipulated with facility.

The foregoing. detailed description has been given -for clearness of understanding only, and no unnecessary limitations should vor be understood therefrom, but the appended claims should be construed as broadly. as permissible, in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is:

1. In means of the character set forth, the combination of a. bracket provided with a channel, a coiled Wire Vmember extending into said channel, and a pin entered in seid coiled wire member within said channel and.

Vcausing; cramped engagement between said channel and coiled wire member.

2. In means of the character set forth, the

combination of a curtain-rod rovided with coiled wire end portions, brac ets provided with channels receiving sald end-portlons,

c and members extending into the ends of said coiled wire portions and serving to cause cramped engagement'between the same and the walls of said channels.

3. The combination with. a, curtainrod having a flexible coiled Wire end-portion, of a bracket provided with a curved channel receiving said coiled Wire end-portion,V and e Leitende pin entered in the end of said coiled wire 25 portionand causingcrampedeV agement between the same and the walls o said curved channel.

4. The combination with a rame, of a.

pair of brackets attached thereto and p ro- 30A vvided with channels, a curtain-rod havlngV Gesine n. enniison.
